What to do if angel trumpet leaves curl?
Solving the problem with curled angel trumpet leaves consists of two stages. The first step is to determine the cause. This results in adequate countermeasures in the second step.

You can read more detailed explanations of proven solution approaches in the following sections.
- Cold causes angel trumpet leaves to curl.
- When drought stress occurs, the leaves curl up.
- Brugmansia react to pest infestation with curled, curled leaves.
How do I protect the angel trumpet from the cold?
Angel trumpets do not tolerate frost. The magnificent ornamental trees come from South America. Far away from their subtropical home regions, Brugmansia shiver as soon as the thermometer drops below 10 degrees. If you clear it out too early in spring or put it away too late in autumn, the frost-sensitive angel's trumpet will result in curled leaves.
You'll be on the safe side in spring if you clear out your angel's trumpet in the second half of May. A minimum-maximum thermometer is suitable for determining the autumn clearing date. The lowest temperature of the previous night can be read on the scale.
What to do if leaves curl due to drought stress?
Regular watering covers the high water consumption of thirsty angel trumpets. Under the influence of summer heat and warm winds, the soil in the pot can dry out very quickly. Plants signal drought stress with curled leaves. A finger test clears up any remaining doubts about the dried out substrate. This is what you need to do now:
Fill a tub with water. Place the bucket in the water until no more air bubbles appear. Lift the container out of the water and let it drain on a rack. If the immersion bath fails due to the weight of the angel's trumpet, please water thoroughly. The measure is successful if the curled leaves straighten within an hour.
How do I control pests on an angel trumpet?
Aphids and spider mites don't care about the toxic ingredients in an angel's trumpet. The pests unscrupulously colonize the leaves in order to suck the cell sap. Typical symptoms of the infestation are speckles, curled leaf edges and curled leaves. With these home remedies you can fight aphids and spider mites on the angel's trumpet:
- In the first step, rinse the leaves vigorously.
- In the second step, spray all tops and bottoms of the leaves with soft soap solution.
- Add 30-40 ml of soft soap and 1 tablespoon of spirit to 1 liter of water.
- Repeat the treatment every two to three days until no more pests are detected.
Tip
Do not water angel trumpet with rainwater
Angel trumpets have an aversion to rainwater. In this respect, Brugmansia differ from most tropical ornamental and container plants. In fact, an angel's trumpet consumes lime. If irrigation water does not supply lime, deficiency symptoms will occur. The pH value of the substrate drops to such an extent that the nutrient supply comes to a standstill. For this reason, please water your angel trumpet predominantly with normal tap water.
